Title: Process and device for the manufacture of pressed electrodes for arc welding
IPC: B23K35/40
Filed: 1937-12-10
Abstract: 511,182. Coating welding-electrodes by extrusion. LANGE, K., and LANGE, F. Dec. 10, 1937, Nos. 34291 and 34292. Convention dates, Dec. 10, 1936, and Dec. 1, 1937. [Class 87(ii)] Arc welding electrodes are produced by feeding wire rods one in front of the other from a magazine through an extrusion coating nozzle, the contact ends of the rods being rendered free from coating, and the forward movement of the rods being interrupted after travelling a rod length, whilst a removing device conveys the rods from the nozzle without interruption and places them on a drying band. Wire rods in a hopper 1 are loosened by two pairs of roughened rollers 2 which tend to lift the rods and the rods then pass down a narrow passage 3 to two feed rollers 4 which have a portion of their circumferences flattened to receive the rods. The rollers 4 feed the rods forward through the guide tube 8 to the extrusion nozzle 10. The un-flattened circumference of the rollers 4 is preferably equal to one rod length but if it is less an additional pair of feed rollers 7 is provided. The width of the passage 3 and the distance between the rollers 4 and 7 may be adjusted to suit the size of the rods. A knife or a current of compressed air may be provided outside the nozzle 10 to remove the coating from the contact end. Alternatively an annular membrane 11 of sheet metal is provided within the nozzle head which is expanded by pressure from a hydraulic ram 22. A cam disc 28 operates the ram in conformity with the feed of the rods so that when the rods are stationary the pressure is suddenly reduced thus enlarging the space in the nozzle head and stopping the flow of coating material. The coated rods are removed from the nozzle by a continuously running band 14 which thus spaces them apart and are then transferred to drying bands 29 by a hook-shaped seizing device 16 which is reciprocated by a crank 21 and lever 20 along a guide track 18 and is simultaneously swung from one side to the other so as to pick up the electrode and deposit it on the bands 29. All the parts are driven from a common shaft 26.

Abstract: 897,447. Nuclear power plant. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 21, 1959 [Oct. 28, 1958; June 4, 1959], Nos. 34412/58 and 19146/59. Class 39(4). In a heavy water moderated, steam-cooled, nuclear reactor power plant, water is vaporized in heat exchangers heated by superheated steam from the reactor, which is supplied with vapour from the exchangers. The reactor superheated steam outlet temperature is maintained constant by a control rod positioned automatically in correspondence with a temperature error signal. The moderator water is temperature controlled by circulation through a cooler. The heat supply to an auxiliary feedwater heater is automatically raised as the turbine pressure falls. As shown in the Figure accompanying the Provisional Specification, the reactor 1 supplies superheated steam to the turbine 6. The condensate from condenser 7 is transferred, by pumps 8, 10, to the evaporators 2, 3, 4, 5 the saturated steam output from which passes to the reactor where it is superheated. From the reactor the superheated steam passes cyclically through 2, 3, 4 and the reactor before flowing through 5 to the turbine.

Title: Improvements in grease guns
IPC: F16N3/12
Filed: 1935-12-16
Abstract: 469,076. Grease guns. ZIMMT, E. R. (Hahn, H., and Fuhrmann, P.) Dec. 16, 1935, No. 34856. [Class 102 (i)] In a grease gun of the type in which a highpressure cylinder a, Fig. 1, is supplied by a coaxial reservoir d, the piston f of the reservoir is acted on by compressed air supplied by an air-pump incorporated in the gun. As shown, the cylinder a is secured in a sleeve 30 carried by the reservoir and the grease is supplied to the cylinder a through a passage 31 and the annular space between the cylinder a and the sleeve 30. An annular piston k moving in the space between the sleeve 30 and an outer sleeve m supplies air to the upper side of the piston f through passages 24, i. The high-pressure plunger b is forced into the cylinder a against the action of a spring 20 and carries an outer sleeve 19 which operates the piston k. In a modification air is supplied to the lower side of the piston f, and the grease is forced through the tube i to the cylinder a. In a further modification, Fig. 7, the high-pressure cylinder discharges to a space 43 and through a passage c having a ball-jointed extension 17. The pressure in the space 43 acts on a piston 15 connected to the air-pump piston k and effects the suction stroke of the latter, the discharge stroke being effected by a spring 13. The air is discharged past a sleeve-valve o to the lower side of the piston f, and the grease is supplied to the high-pressure cylinder through the annular space between a sleeve e carried by the lower cover of the reservoir d and a sleeve 1 carried by the reservoir. For refilling, the reservoir is unscrewed from the lower cover and is removed, together with the sleeve 1 and the high-pressure plunger b, which is operated by a handle p. In a modification the grease pressure effects the discharge stroke of the air-pump piston.

Filed: 1928-11-27
Abstract: 316,829. Macfarlane, J. C., and Macfarlane, W. A. Nov. 27, 1928. Pole-pieces.-In a development of the invention described in Specification 293,508, the field poles are not divided, but are so arranged that the air gap under the leading tip is greater than that under the trailing tip so that under short-circuit conditions the cross flux due to armature reaction will saturate the armature teeth under a part of each pole and thereby reduce the total flux passing through the armature from pole to pole to an amount which is just sufficient to keep the short-circuit current circulating in the armature winding. In one arrangement, Fig. 1, a pole of normal shape is tilted, and the trailing tip is cut away to leave a surface T, M parallel with the armature. Fig. 2 shows a modification in which part of the leading tip L, M is set back parallel to the armature. The part T of the pole may have a restricted cross section to increase the reluctance. Interpoles may be used for improving commutation, for varying the characteristic or for stabilizing the machine as described in Specification 293,508.

Filed: 1936-12-19
Abstract: 484,018. Feeding sheets. BACKHOUSE, H. T. Dec. 19, 1936, No. 34963. [Class 100 (i)] In a sheet-feeding device of the kind in which the sheets are, one at a time, partly lifted from the top of the pack, stretched at the portion lifted, and forwarded in a direction parallel to the top of the pack, the operations of lifting, stretching, and forwarding of the sheets are effected by a single set of sheet grippers, e.g. suction grippers 1 each of which moves in a direction towards and away from the pack to lift the sheet, in a direction along the top of the pack to forward the sheet, and one of which is movable in a direction transverse to the feeding motion to stretch the sheet. The suction gripper 1 is mounted on a rod 9 carried by guides 10 on the arm 2 of a bellcrank lever which is operated by a cam 4 to move the gripper 1 to and from the pack. The gripper is moved longitudinally along the guides 10 by means of an oscillating bell-crank 3 operated by a cam 5 formed with a slotted end 12 embracing a pin 13 on the rod 9. A cam 16 on the lever 3 permits the gripper 1 to move outwards under the action of a spring 17 by permitting the rod 9 to turn on its axis owing to the movement of an arm 14 fitted with a roller 15 engaging the cam 16. The grippers may be moved backwards after gripping the sheet prior to the forwarding movement. The invention is especially applicable to stream feeders, and when the grippers operate at the rear edge of the pack the separation of the sheets may be assisted by combing wheels or bucklers, air blasts directed under the lifted edge of the sheet, and presser feet arranged to rest on top of the pack underneath the lifted sheet. Specifications 399,209 and 427,041, are referred to.
